In this paper, I pose a problem for Hitchcock's arguments for two concepts of effects that are intended to explicate double causal effects, and put forth a theory that is intended not just to meet the problem but also to accommodate Hitchcock's theory and Eells' theory both. First, I introduce an example of dual causal effects, and examine the accounts of Otte(1985) and Eells(1987) on how to explicate the dual effects. I show that their accounts of the dual effects help us understand the problem of dual effects and see how different it is for Cartwright(1979, 1989, 1995), Eells(1991, 1995), and Hitchcock(2001a) to meet the problem. Second, I introduce two concepts of effects on Hitchcock(2001a), that is, net effect and component effect that are allegedly analogous to two effects of structural equation model. Third, I reveal the significance of homogeneous subpopulation and causal interaction regarding the problem of dual effects while examining Cartwright's theory and Elles' theory. Fourth, I critically examine the two concepts of effects on Hitchcock and argue against Hitchcock's criticism of Eells' theory. Fifth, I take a moderator variable of structural equation model and a moderator effect into the probabilistic theory of causality, and formally generalize causal interaction due to the dual effects in terms of disjunctive relation and counterfactual conditionals. I expect my account of disjunctive relation and counterfactual conditionals to contribute not just to several problems the received theories of causal modelling confront but also to the structural equation models many people exploit as a promising statistical methodology.

This study investigates the effect of consumer involvement in the relationship between customer satisfaction and loyalty (which is measured as consumers' repurchase and WOM intentions). Previous research has presented inconsistent implications on the role of consumer involvement in the relationship. Some researchers have presented the empirical results showing that consumer involvement moderates the relationship, whereas others have done the empirical results implying that the consumer involvement does not moderates. In sum, the previous empirical studies have provided the inconsistent empirical results that consumer involvement may be a moderator or a non-moderator in the relationship between customer satisfaction and loyalty. Thus, we start this research with two research questions: "Does consumer involvement has a moderation effect on the relationship between-customer satisfaction and loyalty across various service industries?" and "Can the moderation effect of consumer involvement be detected differently depending on the statistical methods used to probe the moderation effect?" A questionnaire survey was conducted in the context of four service categories: eight service firms for fast food, four firms for family restaurant, four firms for movie theater and four firms for Bakery. Hierarchical regression analyses (moderated regression analyses) and chi-square difference tests were used to identify the role of consumer involvement in the relationship between customer satisfaction and loyalty. The empirical results show that there does not exist the difference in the moderation effects of consumer involvement identified by the two statistical methods (i.e., hierarchical regression analyses vs. chi-square difference tests), however, that there exists the difference in the identified moderation effects of consumer across service categories. In the final section, we summarize the implications and re-interpret the empirical results provided in the previous studies.

The purpose of this study is to investigate how perceived risk of Chinese street foods affect on eating intention and verify the moderator effect of food neophobia between them. To test study hypotheses, we apply a logistic regression analysis and a hierarchical logistic regression analysis. The findings and implications can be summarized as follows. First, Korean tourist perceived hygienic risk on Chinese street foods most highly, followed health risk, social/psychological risk. Second, while perceived health or social/psychological risk on Chinese street foods has s significant and negative effect on eating intention, but perceived hygienic risk has no significant effect. Third, there is a evidence to support moderating effect between perceived hygienic risk and eating intention of Chinese street foods.

Objective: This study aimed to investigate the effect of parent- teacher communication on childcare teacher's job stress and turnover intention. This study also examined if the level of active stress coping used functions as a moderator in relationships among parent-teacher communication, childcare teacher's job stress, and their turnover intention. Methods: To achieve this, this study used data from 223 surveys from childcare teachers and analyzed the data with SEM and multi-group SEM analysis methods. Results: First, parent-childcare teacher communication influenced the teacher's turover intention through job stress. Second, the effect of parent-childcare teacher communication on job stress was not found in the higher-level of the active stress coping group. This was different from the significant effect in the lower-level of the active stress coping group. Also, parent-childcare teacher communication influenced teacher's turnover intention through job stress in the lower-level of the active stress coping group. In contrast, the mediation effect was not shown in the higher group. Conclusion/Implications: The results of this study show the effect of parent-childcare teacher communication on teacher's job stress and their turnover intention. Also, this study shows that the level of active stress coping could moderate the relationship among parent-childcare teacher communication, teacher's job stress, and their turnover intention.

This study analyzed the effect of flight stress on job satisfaction and safety culture on 193 domestic civil airline pilots. As a result of the analysis, flight stress had a negative effect on job satisfaction, and pilots with low job satisfaction had a low awareness of safety culture. In particular, there was a difference in the effect of flight stress on job satisfaction and safety culture according to the airlines and rank of pilots. This suggests the necessity of developing customized stress management programs for each airline and pilot position. The study emphasizes the importance of managing pilots' stress and improving job satisfaction to reinforce the safety culture of the aviation industry. In addition, airlines should develop strategies to strengthen safety culture by reducing pilot stress and increasing job satisfaction. The result of this study is to be used as useful basic data for finding ways to manage pilots' stress and strengthen safety culture in the aviation industry.

This study conducted a meta-analysis to examine syntagmatically on the variables related with recovery among persons with mental illness in Korea. In order to do a meta-analysis, theses and dissertations published between 1999 and 2018 in Korea were reviewed systematically and a total of 24 including studies were selected. Using Comprehensive Meta Analysis (CMA) 3.0 software, this study calculated average effect size and moderator variables related with recovery among persons with mental illness. Results were as follows. First, this study identified a total of 16 variables related with recovery among persons with mental illness. Second, the results indicated that variables which showed large effect sizes included social support(r=.575), empowerment(r=.555), self-efficacy(r=.544), social skill(r=.500), relationship with social worker(r=.482), stigma(r=-.446), family support(r=.418). Third, variables with medium effect sizes included interpersonal relationship capacity (r=.391), agency service satisfaction(r=.366), insight(r=.373) and symptom(r=-.239). Fourth, variables with small effect sizes included work experience(r=.188). Fifth, moderator analyses were conducted utilizing characteristics of residence state (community or mental hospital). Moderator effects were identified in the social support and family support. Based on the findings, theoretical and clinical implications for the recovery among persons with mental illness in Korea were discussed.

This study examined the social support of the physically disabled persons(PDP) and stress coping behaviors as the factor determining their Community Participation. It also analyzed the possibility of such social support influencing their community participation using their stress handling ability as a moderator. The analysis first revealed that the social support for PDP is a positive variable influencing their community participation. Second, the social support has a positive effect on their stress coping behaviors. Third, their stress coping behaviors had a positive effect on their community participation. Fourth, the social support, partially serving as a moderator for boosting their stress coping behaviors, had a positive effect on their community participation. Based on these findings of this study, a proposal for PDP's community participation was made.
